To express a number in scientific notation, we need to move the decimal point and represent said number with a multiplication by a power of 10.
We can see one simple example:
the number 3 in the power of 10, represents that we move the decimal point 3 places to the left.
In this case, we have the number 62,540. We can represent this in scientific notation if we move the decimal point 3 times to the left:
and since we move it 3 places, the power of 10 will be 3, and the answer is:
